Working for AT&T tech support is pretty straightforward. You show up, log in to your phone and you tools, and begin taking calls. It's pretty strict when it comes to the rules. Either you follow them, and you advance, or you don't, and you leave. The management of the call center itself is pretty great. They are willing to listen and work with any issue employees had, no matter where you stacked up in term of responsibility. It's not the easiest job though, and it requires a very particular mindset. There will be days where everyone who calls in will want to bite your head off. But on the flip side, there are plenty of customers I won't soon forget, because the time on the phone with them was enjoyable. Overall, I think as a starting place to get experience in a call center environment, there are few places better.
